mysql – LOAD DATA INFILE使用STR_TO_DATE转换2个日期(@ var1,’％m /％d /％Y’) – 抛出错误

LOAD DATA LOCAL INFILE 'H:/Data/DB__Muni/data/msrb_AZ_short1.csv'
INTO TABLE import_mdrp FIELDS TERMINATED BY ';' LINES TERMINATED BY '\r\n' 
  ( 
    Issuer, cusip6, state, Issue,

SET maturity = STR_TO_DATE(@var2,'%m/%d/%Y') 
SET issue_date = STR_TO_DATE(@var1,'%m/%d/%Y') 
;

SET maturity = STR_TO_DATE(@var2,'%m/%d/%Y') 
SET issue_date = STR_TO_DATE(@var1,'%m/%d/%Y') 

尝试

SET maturity = STR_TO_DATE(@var2,'%Y-%m-%d') 
SET issue_date = STR_TO_DATE(@var1,'%Y-%m-%d') 

更新1

SET maturity = DATE_FORMAT(STR_TO_DATE(@var2, '%m/%d/%Y'), '%Y-%m-%d'),
    issue_date = DATE_FORMAT(STR_TO_DATE(@var1, '%m/%d/%Y'), '%Y-%m-%d')
